TO ALL WHOM IT MAY CONCERN:

Be it known that I, H. H. ETTER, of the cityof Washington, and District of Columbia, have invented a new and useful Improved Burning Fluid; and I do hereby declare the following to be an'exalct description thereof.

The nature of my' invention is the use of ingredients, added to naphtha and other burning oils, to give a. body to the oil or prepared fluid that makes the fluid burn with a. more brilliant flame, burns longer, does not flare upthroughthe eh'in'iney, as the-common coal oil, but burns with a more steady light, and not liable to explode, and much safer for use.

I mix the ingredients and make my burning fluid as follows;

To fortygallons of naphtha (of gravity from 62 to 65) I add two quarts of oil of vitriol, three half pints of linseed oil. These ingredients areputinto a barrel withthe naphtha, and shaken well together, and left to settle for eight days. I then reek it oil into another coal-oil barrel, and addthe following ingredients in the following proportions: First draw ofl' five gallons of the naphtha into another vessel, and mix with it two pounds of white-ook bark, ground, and a. half pound of henilook bark ground, and one and ahalf pound of slippery-elm bark, also ground, and one pound of sassafras bark of the roots, (to destroy the smell of the benzine,) letting this mixturev remain for ten hours and stirring it frequently, then straining the \vhole'throngh.

a cloth, and add it to the barrel of naphtha, and intwenty-four hours it is reody for use.

' What I claim as my invention, and desire to secure by Letters Patent, is I The ingredients, when mixed in the proportions as herein specified, for the purpose of producing a safe and brilliant light.

H.- H. ETTER.
